My inventionfurther resides. inthe combination, construction and arrangment of parts illustrated in the accompanying drawings and while I have shown therein a preferred embodiment, it is to be understood that the same is suceptible of modification and change, without departing. fromr the spirit ofmy'invention.

Referring to the drawings: l Fig. 1 is a view in front elevation of a heater or furnace using bands or 4rings constructed in accordance with the invention;

Fig. 2 is a fragmentary View in perspective of ,a band or ringl for connecting the furnace walls. s.. Y

Fig. 3 is a vertical cross-sectional view through the band or ring on the line 3-3 of Figs. 4v and 5` are fragmentary vertical cross ,sectional views through alternate forms of the band or ring. y v

`Referringnow more in particular to the disclosure shown in Figs. r1, 2 and 3 of the drawings, the numeral l-designates a band or ring, the band or ring comprising an annular head or rib 2 which acts as a support or separating member between the sections of the outer walls 3 and 4; intermediate flange portions 5, which actas spacers to separate the outer walls. 3and 4 from the inner walls 6 and 7 respectively; andinner flanges 8, the joinder of thek inner flanges 8 with the intermediate flangev forming shoulders 9 which act as a support or separating `member between the sectionsl 6 and 7, as shown in Fig.. 3. The rib or 4head portion 2v of-the band 1 will extend outwardly- Vand maybe of any desired shape or design,

and. is; provided i with shoulders 10. The moulding or bead 12, the inner faceof which conforms to` theshape of the head, is pro-j vided with flanges 11 which abut theoutside walls 3 and 4 lof the furnace, thereby forming a very compact j oint and shoulder. n This bead or moulding 12 may be made in sections of any desired length, andof anysuitable material so that theyV may be sprung or forced over the rib or annularhead 2, thus forming a very compact joint at the point where the iianges 11l strike or abut the outer walls`3 and 4. This bead or mouldf ing, when sprung or placed over the annular head or rib will also force thefends of the walls 3 and 4 in contact with lthe shoulders 10 thereby securing a very tight joint. This bead or mouldingv may also be decorated Yas desired. l

It will also'be seen that the inner ,facev (of. the intermediate flanges kis in Contact ,with the outside face of the inner wall; This has been done to prevent the escape' of gases,

Vheat or other elements intothe chamber between the outer and interior walls.

In 4the alternative form of band or ring, disclosed in Fig. 4, 13 designates a channel shaped annular rib or head which acts-.as a supporting or separating member between the ksections of the outer walls 3 andy4; intermediate flange portions A14, which act as spacers to separate the outerv walls 3 and 4 fromthe inner walls 6 and f respectively; bent portions 15; and inner flanges 16,- the bent portions 15` at the point of joinder of the intermediate flanges 14 and the inner,- ianges acting as shoulders whichj'support or separate the sectionsx and 7 of theinte rior walls of the furnace. As in the embodiment in Fig. 3, vthis, channel shaped annular sok rib or head extending outwardly, may be covered by a moulding or bead of any shape or design and adapted to butt against the sections of the outer walls 3 and 4 and attached thereto by any suitable means. The bead or moulding may be made of any desired material and may be made in sections of any length and upon which may appear designs or enamel or other coatings applied thereto.` As in the embodiment shown in F ig. 3, the inner face of the intermediate flange 14 is in immediate contact with the outer face of sections 6 and 7 of the inner walls thereby forming a very effective joint to prevent the escape of gases or other elements.

In the further alternative form of the annular band or ring disclosed in Fig. 5, 17 refers tothe head or rib comprising two outwardly protruding members 18 circumferentially in contact with each other along their entire length, the portions 19 being bent inwardly and angularly into the air A chamber between the sections of the walls 4 chamber of the furnace, forming the shoulders 21 which support or separate the sec- 3 and 6, and 4 and 7, forming the shoulders 20, which act to support or separate the sections of the outer walls 3 and 4; the portions a being bent; inwardly into the inner tions of the walls 6 and 7 and in their bent and extended portions form the flange shapedportion 22 which provides or forms an air chamber within the ring or band itself. As in the embodiment, disclosed in Fig. 3, the outwardly protruding head 17 may be enclosed with a moulding or bead of any shape or design and adapted to butt against the sections of the outer wall 3 and 4 and attached thereto by any suitable means. lIt will be seen that the end of the members 19 are in contact with the inner walls and are positioned in such a way as n to provide flexible or springing means to keep the sections of the inner walls 6 and 7 in close vcontact with the shoulders 21, thus forming a very efficient and neat joint at this point and preventing gas or other elements from escaping into the air chamber formed bythe space between the outer and.l

inner Walls 3 and 6 and 4 and 7, respectively. While I have herein described and upon they drawings shown a preferred embodi-` k ment and alternate forms in my invention,

it is to be understood that it is not limited thereto, but comprehends other constructions, details, features and arrangements of `parts without departing from the spirit thereof.

Having thus described the invention, I claim:

1. A joining means for a double wall furnace` comprisinga circumferential piece having an outwardly protruding annular rib and laterally extending intermediate flange 2. A joining means for a double wall furi nace or the like, comprising a circumferential piece having an outer rib, the side portions of said piece being bent to form spaced shoulders for receiving the inner and outer walls of said furnace.

3. YA joining means for a double wall furnace or the like, comprising a circumferential piece having an outer rib, the sides of said piece being bent to form flanges intermediate of the walls of said furnace and to further provide flanges interiorly of said furnace.

n 4. A joining means for a double wall furnace or the like, comprising a circumferential vpiece having an outer rib,l the sides of said piece being bent outwardly to provide a shoulder' for seating the outer' wall of said furnace, the sides of said piece being further bent to provide another shoulder for seating the interior walls of said furnace.

5. A oining means for a double wall furnace or the like, comprising a circumferential Vpiece having an outer rib, the sides of said piece being bent to provide spaced shoulders and flanges, said shoulders adapted to support the walls of said furnace, one of said flanges being interposed between andv for separating said walls.

6. A joining means for a double wall furnace or the like, comprising a circumferential piece having an outer rib, the side portions of said piece being bent to provide intermediate and interior flanges having a shoulder therebetween for receiving the inner wall of said furnace, the intermediate flange having a face thereof flush with said wall.

7 A joining means for a double wall furnace or the like, comprising a circumferential piece having an outer rib, the side portions of said piece being bent to provide intermediate and interior flanges, said intermediate flange being interposed between the inner and outer walls of said furnace for separating the saine, said intermediate flange having a part in contactwith the inner wall for preventing escape of gases from said furnace.
